Advanced Parameters, continued:

- Zero-cross delay: how long after the zero crossing is the AC line sampled by the POP Trigger. Default value is suitable for 50-60 Hz AC line. Adjust for a different line frequency.
- Blanking delay: The delay after which the PFC POP Trigger commences to characterize and synchronize the circuit during a transient analysis. Increase this value to e.g. activate the PFC POP Trigger only once the circuit has settled after start-up or a transient.
- Hold DAC_IC value: Check this box to make the PFC POP Trigger output a constant current corresponding to the entered DAC IC value during an entire transient. This stops the PFC POP Trigger from synchronizing. Checking this box and setting DAC IC = 0 is equivalent to disabling the PFC POP Trigger.
